Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a detergent for cleaning tire wheels and a method of cleaning tire wheels with the detergent, more particularly to a detergent for cleaning tire wheels which enables one to recognize the point when its ability to remove grime becomes lost with eyes and a method of cleaning tire wheels with the detergent.

2. Description of Related Art

Tire wheels are mounted on tires of automobiles and hence a variety of grime can be deposited on the tire wheels in an amount increased with time.

For example, brake disks are mounted near the wheels, and dust particles produced from the brake pad or brake lining are deposited on the tire wheels. Furthermore, the wheels splash mud on themselves during the running of automobiles. When automobiles run on asphalted roads, fine particles of petroleum products such as pitch are also deposited on the wheels. Thus, a variety of grime can stick onto the wheels.

The grime sticks onto the tire wheels in the following manner: dust particles themselves rubbed off from the brake pad or brake lining do not stick onto the wheel surface. The materials derived from air and/or roads act as an adhesive to allow the dust particles adhere to the wheel surface.

Dirty tire wheels are washed with a surfactant-based detergent. In this case, the detergent is sprayed onto the wheels in a foamy state. The foamy detergent-applied wheels are left standing as it is for a while. Thus, the materials for adhering the metal particles, stone particles and petroleum solid particles onto the wheels are wetted with the foamy detergent, thereby allowing the foamed detergent to take these particles therein, and then allowing these particles to leave the surface of the wheels or float over the surface of the wheels. Finally, the foamy detergent takes the grime particles therein.

Thereafter, the detergent can be wiped off or removed away by water.

However, it is uncertain to users or customers how long it requires for the detergent to swell the grime, penetrate in to it and finally remove the dust particles, mud and petroleum product particles from the wheels. Furthermore, the time required for the detergent to eliminate these particles varies depending upon the deposited amounts of the particles and/or applied detergent. In short, in eliminating an entirety of grime sticking onto the wheels, it is uncertain to users or customers what amount of detergent should be used, and how long the detergent should be left on the wheels before removed away.

Therefore, nowadays an amount of most commercially available detergents used has to be measured by eyes, and the applied detergents have to be removed in a time decided by users themselves by guess.

There may occur such problems that the tire wheels are not well cleaned because of the time decided being too short or damaged with the detergent because of the time decided being too long.

SUMMARY OF THE INVENTION

The first object of the present invention is to provide a detergent for cleaning tire wheels, which enables one to easily know the timing for removing the detergent, in which the grime adhered to the tire wheels is included, from the wheels by color change of the detergent, and to provide a method of cleaning tire wheels with the above-mentioned detergent.

The second object of the present invention is to provide a detergent for cleaning tire wheels, which enables one to accurately recognize the point when the detergent's ability to remove grime becomes lost, and gives a high degree of cleaning effect without damaging the tire wheels, even though the detergent is left on the tire wheels for a long time, and to provide a method of cleaning tire wheels with the above-mentioned detergent.

DISCLOSURE OF THE INVENTION

In a well-known tire wheel cleaning method, a foamy detergent is applied onto a tire wheel having grime adhered thereto, and then the grime is released with the foamy detergent from the surface of the tire wheel. According to the present invention, the detergent is featured by comprising a surfactant, at least one alkali compound selected from the group consisting of ammonia and amino group-containing alkali compounds, and a color change indicator capable of changing its own color when turned from an alkaline condition to a neutral condition, and the alkali compound is contained in the detergent in such an amount that the compound is eliminated from the detergent by reaction with carbon dioxide for the same period of time as required to release most amount of grime from the surface of tire wheels.

In one embodiment, the above-mentioned tire wheel-cleaning detergent may contain a color pigment or dye. In another embodiment, the detergent may contain an anionic and/or nonionic surfactant as the above-mentioned surfactant. In a further embodiment, the above-mentioned anionic surfactant may be at least one salt selected from the group consisting of alkylbenzene sulfonates, alkyl sulfosuccinates and mixtures thereof. In a still further embodiment, the above-mentioned amino group-containing alkali compound may be at least one alkali compound selected from the group consisting of morpholine and alkanolamines.

The color change indicator used in the present invention may be phenolphthalein which can change its own color when turned from alkaline condition to acidic condition.

In one of the preferred embodiments of the present invention, the above-mentioned detergent for cleaning tire wheels is applied in a foamy state onto the tire wheels, and the foamy detergent on the tire wheels is removed only when the original color of the foamy detergent is changed to another color.

BEST MODES OF WORKING FOR THE PRESENT INVENTION

The detergent for cleaning tire wheels according to the present invention is applied in a foamy state onto the surface of the tire wheels to swell grime adhered to the tire wheels, particularly metal particles, stone particles, mud particles and particles of materials such as petroleum solid products consolidating the grime, or penetrate into such materials to soften the grime, and then the applied detergent is left to stand for a predetermined time to take the grime into the foam of the detergent, thereby providing the cleaning effect.

The detergent contains the surfactant to obtain this cleaning effect.

As the amphoteric surfactant, reference may be made to N-lauryl -β-alanine, N-stearyl β-alanine, N,N,N-trimethylamino-propionic acid, N-hydroxylethyl. N,N-dimethylaminopropionic acid, N-methyl N,N-dihydroxyethylaminopropionic acid, N,N,N-trihydroxyethylaminopropionic acid, N-lauryl N,N-dimethylamino-propionic acid, N-myristyl N,N-dimethylaminopropionic acid, N-palmityl N,N-dimethylaminopropionic acid, N-stearyl N,N-dimethylaminopropionic acid, N-hexyl N,N-dimethylaminoacetic acid, N-octyl N,Ndimetylaminoacetic acid, N-decyl N,N-dimethyl-aminoacetic acid, N-undecyl N,N-dimethylaminoacetic acid, N-lauryl N,N-dimethylaminoacetic acid, N-myristyl N,N-dimethylaminoacetic acid, N-palmityl N,N-methylaminoacetic acid, N-stearyl N,N-dimethylaminoacetic acid, 1-pyridium betain and 1-α-picolinium betain.

As the nonionic surfactant, reference may be made to nonionic surfactants of an ether type, ether-ester type, ester type and block polymer type and a nitrogen-containing nonionic surfactant.

The nonionic surfactant of a block polymer type may be surfactants of a Pluronic type and of a Tetronic type and an alkyl; group-containing block polymer.

The nitrogen-containing nonionic surfactant may be polyoxy-ethylene-fatty amide, alkylol amide and polyoxyalkyl amine.

Of these surfactants are preferred the anionic surfactant and nonionic surfactant. Of the anionic surfactants are preferred the alkylbenzene sulfonates and alkylbenzene succinates. The combined use of the alkylbenzene sulfonates and alkylbenzene succinates is particularly preferred.

In the present invention, the content of the anionic surfactant is normally in the range of 0.1-10% by weight, preferably 4-7% by weight, of the detergent.

The detergent of the present invention contains at least one alkali compound selected from the group consisting of ammonia and amino group-containing alkali compounds, and a color change indicator.

As the above-mentioned amino group-containing alkali compounds, reference may be made to morpholine, alkanolamines, aniline, alkylamines and alkylenediamine. The alkanolamine may be monomethanolamine, monoethanolamine and monopropanolamine. The alkylamine may be ethylamine and propylamine. The alkyl-diamine may be ethylenediamine.

In the present invention, the alkali compound is contained in such an amount that the detergent can turn from neutral to acidic by reaction with carbon dioxide for the same period of time as that required for the detergent to allow the grime on tire wheel to come off from the tire wheel.

That is, when the detergent is sprayed in a foamy state, the alkali compound in the detergent begins to react with carbon dioxide in atmosphere, and concurrently the detergent begins to allow the grime on tire wheels to be softened, swollen and wetted. Thus, the total amount of the alkali compound should be completely reacted with carbon dioxide when substantially whole amounts of the grime adhered to the surface of tire wheels are taken into the foamy detergent.

The cleaning effect by which the grime on the surface of tire wheels is taken into the foamy detergent varies depending upon the composition of the detergent and, therefore, the content of the alkali compound to be contained in the detergent should be experimentally determined for each of the detergents.

In one embodiment of the present invention, the content of the alkali compound may be normally in the range of 0.1-2% by weight, preferably 0.4-1% by weight, for ammonia. In another embodiment, it may be normally in the range of 0.5-3% by weight, preferably 1-2% by weight, for the amino group-containing alkali compound.

If the content of ammonia and the amino group-containing alkali compound is less than the above-mentioned range, the color changing time may be too short to allow the grime to adequately come off from the tire wheels. On the other hand, if this content is more than the above-mentioned range, then an offensive smell may be emitted so that cleaning work is made hard, or an excess of the alkali compound is brought into contact with the tire wheels so that the tire wheels may be damaged.

In the present invention, in order to raise the stability of the alkali compound in the detergent, an alkali salt of an organic acid such as ammonium benzoate, ammonium acetate, sodium acetate, ammonium oxalate and sodium oxalate may be contained in the detergent.

The detergent of the present invention contains a color change indicator capable of discoloring when changed from alkaline to neutral. As the color change indicator, reference may be made to a pH indicator such as phenolphthalein, thymol blue, thymolphthalein and phenol red.

The detergent of the present invention is featured in that it can show the point when the ability to remove the grime becomes lost. Therefore, one or both of a pigment and dye may be used together with the color change indicator. Such pigment or dye may be iron oxide yellow, phthalocyanine green, phthalocyanine blue, brilliant blue FCF, acid red and sunset yellow FCF.

Of these color change indicators, are preferred phenolphthalein and thymolphthalein. To these it is preferred to add phthalocyanine blue as pigment or dye.

The content of the color change indicator in the detergent varies depending upon the content of the alkali compound in the detergent, and should be adjusted so that the color change indicator may have a color under neutral condition when the detergent having been applied to tire wheels turns to neutral. Generally, it may be in the range of 0.001-2% by weight, preferably 0.005-0.2% by weight. If it is less than the range, then the clear finish point cannot be recognized. On the other hand, if it is more than the range, then no additional effect can be expected by the increased amount.

The detergent of the present invention contains water and a water-soluble alcohol as solvent. The water-soluble alcohol may be methanol, ethanol, isopropanol and butanol. These water-soluble alcohols can act as a solvent for the color change indicator. Furthermore, water can also act as a solvent for the detergent.

The detergent of the present invention may also contain a silicone oil, modified silicone oil, liquid paraffin and polybutene for affording water repellency to the cleaned surface of tire wheels. Furthermore, it may contain a hydrocarbon solvent for improving the detergency for oily grime, thereby forming a uniform emulsified detergent.

The detergent of the present invention is prepared by mixing some or all of the above-mentioned components.

The cleaning of dirty tire wheels and recognition of the point when the ability to remove the grime becomes lost can be made by using the detergent of the present invention as follows:

The detergent of the present invention may normally be canned in an aerosol form or packed in a hand-spray container. Furthermore, it may be applied to the surface of tire wheels with cloth and sponge.

In the case where the detergent is packed in an aerosol can or hand-spray container, it is deposited on the tire wheels in a foamy state when sprayed. Directly after the detergent is applied, the alkali compound is not vaporized, and the reaction of the compound with carbon dioxide in air does not proceed and hence the detergent remains alkaline. Thus, the detergent as sprayed has a color. Leaving the foamy detergent on tire wheels will allow the neutralization of the alkali compound with carbon oxide in air to proceed.

The neutralization proceeds to spend the amount of the alkali compound, thereby allowing the detergent to transfer in a neutral condition and change its own color. For example, the detergent turns from blue to yellow in the case where the color change indicator is thymol blue, from pink to colorless in the case where the indicator is phenolphthalein, from red to yellow in the case where the indicator is phenol red.

The change of the detergent reveals that the grime on the tire wheels has been taken into the foamy detergent. Thereafter, the detergent is wiped off or washed away with water.

The present invention will be illustrated below with reference to some examples.
